Alongside developing its own engines, Mecachrome Motorsport also provides subcontractor work, which can include machining, assembly, dyno testing and on-site support, depending on the requirements of the client.

Mecachrome Motorsport is currently a subcontractor for Renault Sport and its V6 Turbo used in Formula 1, as well as Citroen Racing and the R5 engine it utilises in rallying.

In addition to its racing activities, Mecachrome Motorsport also works with ENATA Marine, most recently developing a hybrid powertrain for their FOILER Yacht project.
